Seans, I wish I had all that extra room you have in your engine compartment...if you think yours is tight quarters you should see my LS6 454 shoe horned into my 30 Model A. This is scary tight with no room left over...3/8 to 1/2 inch clearance between the block huggar headers and the frame. Nice looking motor in your hotrod...I had to go to a MSD pro billet distributor because my brand new HEI unit was too tight on the firewall...didn't want to modify the firewall so switched distributors.
